"Writing Machines, of which the followingis a specification.

My invention relates'to cushion feet for typewriting machines. 4

T have devised a foot which can easily be attached to or detached from the typewriter,

composed of a few parts, and is easy to manufacture.

It comprises a cup'in which a compression spring is placed to absorb the vibrations caused by writing upon the machine; said cup having simple means for attachment to the typewriter frame, and provided with a pad.

In the accompanying drawings, Figure 1,

shows part of a typewriter frame with my invention attached. Fig. 2 shows the normal condition of the foot attached to the machine. Fig. 3 shows the foot slightly, telescoped. Fig. 4 shows a perspective of the parts, in which can be seen the construction and assembly. Fig. 5 is another form of cushion.

The foot 1, Figs. 1, 2, 3, 4:, of stable noisedeadening material as felt, for instance, is

fastened to a cup 2, which may telescope over the head of screw 3, fastened. to the underside of the typewriter frame land projecting down therefrom. Inside of the .cup 2 is a cushioning compression spring 5, upon which the head of screw 3 rests. The head of this screw is rat-her thick. Tt is cylindrical in shape as shown in Fig". 4, and is made to fit rather easily inside of and to be a guide to the cup 2. Pendant screws 6,

(Fig. 2) threaded into the head of screw 3, retain the cup 2, and prevent the typewriter from being lifted out of the cups.

Tn the form shown in 5, the foot 1 is fastened to a plate or disk 7, which fits snugly in a cylinder 8, and kept in place by ,a flange 9 screwed to the cylinder. Inside, at the top of the cylinder 8, is a second plate or disk 10. This disk 10, has the same function and is for the same purpose as the head of screw 3. its area of contact with the rectangular head 12, is so extensive that it rests against said head all the time without any tendency to wabble or to become displaced. Below this is acompression spring 5, between the plates 7 and 10. The typewriter hears on the top disk 10 by means of screw 11, which has a rectangular head 12, to be inserted in the slot 13 in the top of cylinder 8, and rest in a groove or pocket 14.

Having thus described my invention, 1 claim:

An attachment for a 'typewriting machine frame consisting of a thick disk-like or cylindrical screw head, a screw shank therefor,

said head being in contact with the underside of the machine frame, a helical spring of about the diameter of the head, bearing against said head, a hollow cylinder fitting over said head and spring and in easy sliding relation thereto, a head at the other end of said hollow cylinder for receiving the downward thrust of said spring and pendent screw-stops taking into the screw head for limiting the movement of said thrust receiving l1G21(l.
